Got First Slides Back- Need Help!

[conan.]

I got my first slides back, from my trip to NYC... some provia and some sensia, all 100. Wondering if I could get some insight as to why my photos are SO grainy and the colors not nearly as good as they should be. My exposures are correct, though... I kept them in the fridge when I wasn't out. However, all of my rolls went through the airport carry-on luggage scanner once. I read that this would be no problem.
I also walked around for several hours a day with a few rolls in my backpack, in the heat. Could these factors have affected the outcome? My BW and negatives all turned out. Maybe it's my lab that sucks?

Will post photos once I upload them.

am beginning to think that maybe the reason is because i asked for the processing, so i have the slides mounted, and i asked for a scan to CD too, and i'm making these judgements based on the digital images... could be just a bad scan? don't even know how scans of slide film work...

anyways, these are some random images...

That would have been my first guess. Do you have a way to examine the slides themselves...like a loupe or slide viewer or projector?

That certainly is a weird grain that you have. I'm not too familiar with grain on slide film, so I don't know if that's normal or what...it doens't really look like typical scanner noise but I'm not sure of that either. :scratch:

First thing is to check if the actual slides are OK.

If you look at your slides on a light box (or hold it up to light) with a loupe, or magnifying glass, do you still see the grain?

I personally think it's just a bad scan..

They kinda do look a bit fogged. The exposures look good, but there's a light glow to them.

I also think it's just a bad scan.

Are those Provia or Sensia slides? I used to shoot Provia 100f a lot and never saw that kind of grain, even on my lightbox with my 8x loupe.

I used Sensia a few times and also never saw that kind of grain.
